LA-RICS Early Deployment System Allows LMR Users to Test Network
Tuesday, August 27, 2019 | Comments

The Los Angeles Regional Interoperable Communications Systems (LA-RICS) implemented an early deployment system consisting of key strategic LMR sites to facilitate communications for early users, while the balance of the network continues to advance in various stages of construction. The early deployment system contains eight interconnected LMR tower sites across the Los Angeles County region.

In August, LA-RICS added a downtown Los Angeles simulcast cell using UHF and 700 MHz channels to provide a digital trunked voice radio system (DTVRS) at the Fire Command and Control Facility (FCCF) and Clara Shortridge Foltz Justice Center, also known as the Criminal Courts Building.

The early deployment system allows users to test and/or use daily the Project 25 (P25) DTVRS capabilities free. When the network is complete, the downtown simulcast cell will include more sites, further enhancing the coverage and capacity in this cell. The final LA-RICS system will provide regionwide coverage and capacity for public-safety subscribers. Additionally, any agency can use the system during emergencies and disasters or whenever they find themselves outside their footprint at no charge.

LA-RICS considers the reliability of the radio tower and equipment shelter foundations critical for lasting and sustainable operations. The recent earthquakes in Southern California are a reminder of just how important solid foundations are to support first responders. All LA-RICS sites are built to support public-safety mission critical grade operational standards, meeting the American Society of Civil Engineers (ASCE) Risk Category IV, the most stringent category available.

Wireless tower category IV sites are identified as structures where failure results in a substantial hazard to the public. Category IV sites include higher design load and seismic load considerations that greatly enhance the likelihood of LA-RICS maintaining communications during natural disasters.
